Flat Roof Types We Install
We’ll recommend the right system for your roof size, foot traffic, and budget, then fit it to a standard you can trust.

GRP Fibreglass Roofing
A tough, seamless finish that suits balconies, dormers and walk-on areas. Ideal when you want a clean look with reliable waterproofing.
Torch-On Felt Roofing
A solid choice for many homes, fitted in layers for dependable waterproofing. Done properly, it’s durable and cost-effective.

New roof on my bungalow - I recently had the pleasure of working with Alliance Roofing and Building to install a new roof on my bungalow, and I couldn't be more satisfied with the results. From start to finish, the entire process was smooth and professional. Mitchell, who led the project, was exceptional. His expertise and dedication were evident from the moment he arrived. He and his team were not only highly skilled but also incredibly helpful and courteous throughout the entire job. They took the time to answer all my questions
Leak in the roof- Very polite and professional. Job was completed professionally at a very good price. Would highly recommend
Tile realignment/repair and felt renewal - Mitchell and his team were excellent. Would definitely recommend Alliance. The team were on time (in fact they were able to begin the job half a day earlier than initially discussed), polite, efficient and kept us informed of progress each day. We could not have asked for a better service.

Frequently Asked Questions
It depends on the system and how well it was fitted, but a properly installed flat roof can last for many years. Regular checks help catch small issues early.
If the issue is localised, repairs are often enough. If the membrane is failing across large areas or the deck is damaged, replacement is usually the smarter long-term fix.
Blocked outlets, split seams, lifted edges, damaged flashing, and ponding water are the usual culprits. The key is fixing the cause, not just covering the symptom.
If it’s urgent, we aim to attend quickly to stop further water ingress and make the area safe, then book the proper repair as soon as possible.
EPDM, GRP, torch-on felt and liquid systems can all work well. The best option depends on roof size, foot traffic, drainage, and budget.
Yes. We’ll explain the options, confirm what’s included, and provide a clear quote so you can make a decision with no pressure.
